Hey all, I am new to the forum (was a guest for a while) and have received some good answers to other questions, thanks! I just bought an 07 YZ450F which has treated me well so far but then last weekend I was at the dunes and had an issue with my paddle tire/wheel. You see I bought a used Warp9 wheel with a paddle online that came off a 09 YZ450F. When I took my stock wheel off, pulled off the spacers to put them on the warp9 wheel I noticed the diameter of the two were different. Basically the warp9 wheel was just slightly larger diameter than the other wheel making it so the spacers dont fit tight. My questions are; is it ok to use them that way? If not, do I buy 09 spacers? is it the rubber gasket in the warp9 wheel that needs to be replaced? THANKS in advance for the help!
